background and purpose:the presence of dyes in wastewaters may cause serious problems for the environment because of their high toxicity to aquatic organisms and unfavorable aesthetical impact. in the present study, multi-walled carbon nanotubes (mwcnts) were used for removal of anionic dyes direct blue 106 (db106) and acid green 25 (ag25), from water samples. materials and methods:mwcnts were ...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
Background and Objective: Acid dyes are synthetic organic compounds with complicated chemical structures which their treatment are difficult and costly. Discharchig of these dyes into the environmen causes harmful effects on ecosystem and water quality. In this study efficiency investigation of photo-fenton process in removal of acid green 20 dye from wastewater of textile industries was assess...
The interactions between an anionic dye, Acid Green 25 AG and the two cationic surfactants tetradecyltrimethylammonium bromide TTAB, and hexadecyltrimethylammonium bromide CTAB in aqueous solutions far below the CMC are studied using the conductometric method at different temperature. The equilibrium constants and other thermodynamic functions for the process of dye-surfactant ion pair formatio...
one of the most effective ways to reach yield stability with low input is increasing diversity through utilizing intercrops in agro-ecosystems. a field experiment based on a randomized complete block design with six treatments and three replications and two crops, green pea and nutrifed millet, was carried out at research farm of agriculture and natural resources of kerman during growing season...
to study the effects of different fertilizing systems using green manure and zeoponix on grain yield and its components in sunflower, an experiment was conducted at the research farm of collage of agriculture, tarbiat modares university in 2010 and 2011. the experimental treatments were arranged as split plot design on the base of a complete randomized block design with three replications. two ...
Background & objectives: The release of dyestuff wastewaters produced in textile industry into receiving waters affects both human health and the environment. The aim of this study was to investigate the efficiency of a photocatalytic UV/persulfate process in removal of methylene blue and acid green 3 dyes from aqueous solutions. Methods: The current study was an experimental study, in which t...
Green cotton (Gossypium hirsutum L.) fibers were shown by electron microscopy to have numerous thin concentric rings around the lumen of the cell. These rings possessed a lamellar fine structure characteristic of suberin. LiA1D(4) depolymerization and gas chromatography-mass spectrometry analysis showed the presence of a suberin polymer in the green cotton with the major aliphatic monomers bein...
